C Programming Final Assignment

Instructions

1) Design and write 6 C programs for the problems, and submit 6 C source code

files with the .c extension. Please do not use the .cpp extension, that is, you are

not allowed to use the C++ syntax.

2) Write a report which includes your commented C code, screenshots of test

results for each problem (run your code and show results). You can prepare

your report in a Word file, convert it into a pdf file, and submit the report pdf file.

3) Reminder again: you should submit 6 commented C source code files and 1

report pdf file on Canvas, i.e., a total of 7 files. You can either submit 7 individual

files, or compress the files in a zip file and submit the compressed file.

4) The submission link is Software Exercise XVAC Week 3

https://canvas.sussex.ac.uk/courses/25884/assignments/100788

5) The due time is 1 Jan 2023 by 17:00 (the UK time)

6) Please also upload your files to OneDrive at the same time if there are problems

with the Canvas server. You can get access to OneDrive through your Sussex

account.

About plagiarism

1) You are not allowed to discuss your coursework with other students.

2) Do not copy the code of other students. Do not let other students copy your code.

3) Do not ask other students for their code.

4) Do not show or send your code to other students. Do not allow other students to

take photos of your code.

5) Protect your personal computer and electronic products. Set passwords

wherever necessary to prevent your documents from being stolen. Report to the

police ASAP if your computers and electronic products get stolen.

Problem 1 (15 marks)

Write a C program to calculate the natural number e with:

lim𝑛→∞

(1 +

1

𝑛

)

𝑛

Print the results with five different values of n which are set according to your

Sussex candidate number. If your Sussex candidate number is 123456, then the

values of n are set as 12, 123, 1234, 12345 and 123456. You can use the loop

structure to solve the problem. You are NOT allowed to use the standard

functions, for instance, the pow function.

Problem 2 (15 marks)

Write a C program that asks the user to input a M * N matrix. M, N, and the

elements of the matrix are entered from the console. The matrix must be created as

a 2-dimensional integer array. Then complete the following tasks:

1) Create and print a submatrix from element (m1, n1) to element (m2, n2) of the

original matrix, where 1≤m1<m2≤M, and 1≤n1<n2≤N. m1, n1, m2 and n2 are

entered from the console by the user. Given an example 4 * 3 matrix A, then the

submatrix from element (2,1) to element (4,2) is B:

𝐴 = [

12 5 22

38 9 40

14 2 54

11 11 33] 𝐵 = [

38 9

14 2

11 11

]

Note: Please do not forget that the indices of the arrays start from 0. Therefore, the index of

element (2,1) in the matrix is (1,0) in the array.

2) After doing task 1), change the values of the four elements in the lower right

corner of the original M * N matrix according to your Sussex candidate number.

If your Sussex candidate number is 123456, the four elements are changed to 12,

34, 56 and 123456. For the above example, the matrix A is changed to Anew, as

shown below. Then print the new submatrix from element (m1,n1) to element

(m2,n2) again.

Problem 3 (20 marks)

Write a C program that defines two unsigned integer variables and assigns your

Sussex candidate number (6 digits) and ZJGSU student number (10 digits) to the

two variables, respectively. Then accomplish the following tasks:

1) Extract the digits of the two variables, i.e. your Sussex candidate number and

ZJGSU student number, and stores each digit as an element of an array of size 16.

The digits of Sussex candidate number are put on the left, followed by the digits of

ZJGSU student number on the right. For instance, if your Sussex candidate number

is 123456, and ZJGSU student number is 2212345678, then the result is

{1,2,3,4,5,6,2,2,1,2,3,4,5,6,7,8}.

2) Count and print the occurrence number of each digit in the array.

Problem 4 (15 marks)

Write three user-defined functions：

1) The first function returns the distance of two points in the 2-dimensional

Cartesian coordinate system.

2) The second function calculates the slope and the third function calculates the

intercept of the straight line that passes through the two points in the 2-

dimensional Cartesian coordinate system.

The coordinates of the two points are given in the main function according to your

Sussex candidate number and they are passed as arguments to the user-defined

functions. If your Sussex candidate number is 123456, then the coordinates of the

two points are (12, 3) and (4,56), respectively.

Call the three functions in the main function and print the results.

Problem 5 (20 marks)

Write a function that computes the roots of the quadratic equation ax2 + bx + c = 0.

This function has four arguments: a, b, c which are the coefficients of the quadratic

equation, and an array of size 2 that stores the two roots. The function returns an

integer variable flag which is set as the following values, according to the number

and type of roots:

0: any x is a solution (a = b = c = 0);

1: wrong equation (a = b = 0, c  0);

2: one root (a = 0, b  0, so the root is -c/b);

3: two roots (b2 – 4ac  0);

4: no roots (b2 – 4ac < 0);

Call the function in the main function and print the coefficients, flag, and roots with

the coefficients below.

(a) 0, 0, 0

(b) 0, 0, 1

(c) 0, 2, 2

(d) 3, 6, 3

(e) 2, 2, -12

(f) 12, 34, 56 (if your Sussex candidate number is 123456)

Problem 6 (15 marks)

Please accomplish the following tasks:

Create an integer array with the following initial values in the main function:

a b c 25 44 1 -27 -119 31 -13 0 23 17 101 -2 324 -7 -39

where a, b, and c are from your Sussex candidate numbers, for example, if your

Sussex candidate number is 123456, then a= -12, b= -34, c= -56.

Write a program that

1) finds the numbers whose absolute values are larger than 20 and stores them

into a second array,

2) finds the negative odd numbers and stores them into a third array,

3) finds the numbers that are divisible by 4 and stores them into a fourth array.

4) creates a text file (.txt file) and writes the four arrays into the file, one line per

array. The file name is your Sussex candidate number. Print an error

message if the file cannot be opened successfully.
